Here you can get four advanced solutions for Steam disk write error/read error, which is a full message displaying as 'an error occurred while updating a game (disk read error)' or 'an error occurred while installing a game (disk write error)'.

About Steam Disk Write/Read Error

As you can tell, the extra information in the parenthesis behind the detailed error message is disk related. So, what disk problems would bring about such failure in daily game update and installation?

In conclusion, the disk write or read error comes, to a large extent, from some bad sectors on your hard drive, or your hard drive is failing and the disk is write protected in aspects of scratches, corruption, virus and specific permissions. Thus, to have Steam disk problems solved, you need to take prompt actions to repair the hard drive in question.

In addition to the basic troubleshooting for Steam disk errors provided by Steam Support, including restart computer, clear download cache, reinstall Steam or move the Steam installation to other location, we come up with four advanced solutions that proved to be more potent in removing Steam disk write or read error thoroughly.

Fix 1: Verify integrity for Steam game files

Try to verify integrity for Steam games files at first if you see games keeps crashing or their models missing unknowingly.

Step 1: Reboot system and then launch Steam.

Step 2: Select "LIBRASY" tab and right click the game that sends disk errors and select "Properties".

Step 3: Click "LOCAL FILES" tab, and then you can see "VERIFY INTEGRITY OF GAME FILES…" button. Click it.

Step 4: Steam starts verifying game files, which may take a couple of minutes. Please note that some files may fail to verify, which is normal for most Stem games. That's because these files are local configuration files and they cannot be disturbed as part of this action.

Step 5: When all files are validated successfully, you can retry installing updates and see whether the disk error is removed.

Fix 2: Remove disk write protection

When a disk is write-protected, you're prevented from modifying it, such as formatting, writing data, installing programs on it. That's the other possible reason why you receive disk errors on Steam. Simply use the diskpart command to clear write protection and remove the error.

Step 1: Open administrative "Command Prompt".

Step 2: Type these commands one by one and press Enter key after each:


list disk

select disk # (# is the number of the hard drive with which you're getting disk error)

attributes disk clear readonly
